Charles Ellicott Commentary Genesis 29:31

"And Jehovah saw that Leah was hated, and he opened her womb. But Rachel was barren." — Genesis 29:31 (ASV)

BIRTH OF JACOB’S ELEVEN SONS, AND HIS DAUGHTER.

Leah was hated. —We must not soften this down too much; for plainly Leah was not the object of love at all. It was her fruitfulness which gave her value in her husband’s eyes, and when this ceased, Jacob utterly neglected her (Genesis 30:15).
